Question

Match the following

Column - I

Column - II

longitudinal stress
a.
Volume changes

Shear stress
b.
Shape changes

Volume changes
c.
Volume does not change

Tensile stress
d.
Shape does not change

$i \to a, d; i i \to b, c; iii \to a, d; i v \to a, d$
$i \to a; i i \to b; iii \to a, d; \dot{w} \to a, d$
$i \to b, c; i i \to b; i i i \to c; \dot{i} v \to a, d$
$i \to b, c; i i \to b; i i i \to a, c; \dot{i} v \to d$

The correct answer is: $i not stretchy rightwards arrow a comma d semicolon i i not stretchy rightwards arrow b comma c semicolon text iii end text not stretchy rightwards arrow a comma d semicolon i v not stretchy rightwards arrow a comma d$

Sol: Directly from the theory. (Here, we assumed that in longitudinal and tensile stress that cubicle and parallelopiped are of the same shape, i.e., both are parallel lepipeds).

Molecular forces exist between the molecules of a liquid in a container. The molecules on the surface have unequal force leading to a tension on the surface. If this is not compensated by a farce, the equilibrium of the liquid will be a difficult task. This leads to an excess pressure on the surface. The nature of the meniscus can inform us of the direction of the excess pressure. The angle of contact of the liquid decided by the forces between the molecules, air-and container can make the angle of contact.
If the excess pressure in a soap bubble is p, the excess pressure in an air bubble is
